This invention relates to a gummed tape dispenser.

An object of the invention is the provision of a device for convenientlyholding, feeding out,

applying and cutting off the gummed tape.

Another object of the invention is to provide a device which is designedspecifically to t conveniently into the hand, for a one-handed operationof feeding out, applying and cutting off of gummed tape.

plied to fragile objects, soft papers or loosely wrapped parcels.

A still furtherobject of the invention is to provide a device forone-handed dispensing of gummed tape which is of such simplified designas to be relatively inexpensive to manufacture and easy to reload andoperate. At the same time it is of a rugged construction with a minimumof moving parts to provide and insure long and satisfactory usage.

Still another object of the invention is to provide a device fordispensing gummed tape designed with the safety feature that the cuttingblade is normally pivoted into a protective pocket, except during thecutting operation.

With the foregoing and other objects in view, this invention comprisescertain novel constructions, cornbinations, and arrangements of parts aswill be hereinafter fully described, illustrated in the accompanyingdrawings, and more particularly pointed out in the appended claims.

The application of adhesive tapesin a manually operated 'device hasheretofore been proposed. However, in certain heretofore known and useddevices, there are certain disadvantages, some of which are theinability of the user to fully manipulate the device with the hand thatholds it, the difficulty in arriving at a design which is tailored tofit the hand and which is small and compact, the complication ofmechanism with resulting difficulty in loading, and a tendency to pulland tear on delicate surfaces with attending inconvenience.

The present invention overcomes these difficulties and provides a devicefor dispensing gummed tape, which is not only small, compact andhand-fitting, but which also permits applying tape to delicate surfaceswithout difliculty. Further, it provides means under control of user tofeed out definite lengths of tape before application and cut off.

As will be hereinafter fully explained, the device, embodying themechanism of the invention, may be used for applying adhesive and gummedtape and for dispensing certain cord or strip materials from a roll orspool. Furthermore, any single unit embodying the invention can be usedfor dispensing several widths or roll sizes of tape.

Referring to the drawings, in which the preferred embodiment of thisinvention is illustrated, I designates a housing upon which ispositioned a cover 2. A hinge pin 3 pivotally mounts said cover 2 on thehousing I. In the sides of the housing I are journal sockets 4. An arbor5 is journalled in said journal sockets 4. This arbor 5 is provided withtransverse ribs 6 to better secure the paper core 'I on said arbor 5. Onthe paper core I is a roll or spool of tape material 8.

A feed roller 9 is mounted upon the housing I in alignment with saidarbor 5. This feed roller 9 is provided with a reduced portion I6, Fig.8, upon which is mounted a pressed on ring Il. There is an annulargroove I2 provided between a portion I3 of the feed roller 9 and thering I I. In this annular groove I2 is rotatably mounted the stripperI4, Fig. l0. This stripper I4 comprises a semicircular body I5 integralwith a jaw I6. 0n the outer edge II of jaw I6 there are serrations forthe purpose of stripping the tape from the feed roll 9 as it is beingfed out and also for guiding the tape downward and outward towards thecut-off blade. The portion I3 of the roller 9, as well as the ring II isalso provided With serrations which prevent the tape from sticking onthe feed roll during the feeding operation.

,On the forward end of the cover 2 is a pocket I8, Fig. 5, in whichpocket I8 is suitably designed cut-o blade I9. This blade is pivotallymounted on pin 20. A spring 39 is also pivotally mounted on pin 20. Thecentral portion of spring 3U ls coiled around said pin 29, and one endof spring 3D bears against the roof of the pocket I8 and the other endbears against the inside of hollow blade I9, as shown. The cover 2 isprovided with a depending lip 2I which forms a protective pocket for thecutting edges 23 of cut-off blade I9 and also serves to strip thecut-off edge of the tape from these cutting edges after the cut-olfoperation. The cutting edges 23 serve to cut off the tape during thecut-olf operation at which time they are caused to pivot out on pin `Iland bear against the tape to cut it as hereinafter described. On thelower portion of the `blade I9 are serrations 2li which facilitate theapplying of the tape to a surface; the serrations 4hold'the tapesecurely from slipping during the cut-off operation and thus hold thetape taut while the cut-off point or edges 23 are pivoted out against itto successfully pierce and cut olf the tape.

The cover 2 is provided with sockets 25, Fig. '7,

which are adapted to receive detents 26 when the cover is to be lockedupon the housing.

In Fig. '7, at 21, is an upstanding portion of the bottom of thehousing; this upstanding portion -is also clearly shown in Fig. 5.

The stripper I4 extends in the path of the tape, as Shown by dotted lineA, Fig. 5. It is prevented from rotating with the feed roll during thefeed out operation by means of the shoulder 3i bearing against housing Ias shown in 5. l-Iowever, if for some reason, it is attempted to causethe tape A to be pulled rearwardly, then `the stripper will grip thetape between the ser- 'rated surface of its jaw Iii and the groove 32 inthe outer end of cover 2 as shown in Fig. 5.

On the cover 2 are surfaces 28, Fig. 5, which act -asfguides for thetape A that passes between said surfaces 28 and onto the feed roller Q.The cover 42 is also provided with an opening 32 through which theperiferal portions of the feed roller 9i andrring II project forengagements by the operator-s thumb.

It is to be understood that the means employed to cut off the tapecauses the tape to more or less be locked between the serrated edge 2liof the cut-oil' blade I9 and the feed roll 9 to be pulled taut as theblade I9 pivots out so that when the cutting edges pivot out against thetape they have a rm surface into which they enter and cut. This actioncan easily be seen by reference to Fig. 5. As blade I9 is biased thedistance between the serrations 24 on it and the surface of the feedroll 9 increases. As a result, since the tape is restrained at bothpoints, it has a tendency to stretch the tape and hold it firm forcutting. Under no other conditions would it be possible to so cut thetape.

assigns In operation, the roll of tape material is placed A Von thearbor 5 and then the arbor 5 is placed in the tape against aforesaidsurface and Vilrmly 4 fastens it, then by further downward pressure, theknife I9 is biased causing the cutting points 23 to sever the tape. Thetape is then held between lip 2| and stripper I4 until the operatorpushes forwardly on the feed roller 9, causing a new supply of tape tobe threaded under the cutter blade I9 and upon the object to be sealed.

While I have described the preferred embodiment of the invention andillustrated the same in the accompanying drawings, certain minor changesor alterations may appear to one skilled in the art to which'thisinvention relates during the extensive manufacture of the same, and I,therefore, reserve the right to make such changes or alterations asshall fairly fall within the scope of the appended claims.
